Parallel read/write extension card?

December 05, 2011, 05:07:53 pm

Following another thread I started thinking about BusPirate extension card that will allow read/write to NAND chips. Probably it will be slower than dedicated(more expensive) devices like ProgSkeet...

BusPirate is the king in the serial IO world(at least for me) with an extension card it will step in the Parallel world too.

So what buffers are suitable?

I suppose you could use a 74xx parallel to serial latch, like the opposite of a 595. It would take some time though to do all the clocking. I think it would be much easier to use a small program in a dev-board to read it out. Is it similar to reading SRAM?

We still have a versatile io expander in the fridge. I should update it and release (as many other thing ;)) it.

Indeed. Pls make sure to add it to the project manager :)
